Question

in PHP, can we do the following ?

class a{
    public $id;
}

can we access this field with something like this,

$x='id';
$aObj=new a();
$aObj->$x=1;//or $aObj->"id"=1

Answer 1

This should be possible:

class a {
    public $id;

    function getId() {
        return $this->id;
    }
}

$x = 'id';
$aObj = new a();
$aObj->$x = 500;

echo $aObj->id, " ", $aObj->getId();

gives: 500 500 (Tested with PHP 5.3)
